#
# Makefile for epgfixer, a Video Disk Recorder plugin
#

# epgfixer
# This name will be used in the '-P...' option of VDR to load the plugin.
# By default the main source file also carries this name.
# IMPORTANT: the presence of this macro is important for the Make.config
# file. So it must be defined, even if it is not used here!
#
PLUGIN = epgfixer

### The version number of this plugin (taken from the main source file):

VERSION = $(shell grep 'static const char VERSION\[\] *=' $(PLUGIN).c | awk '{ print $$6 }' | sed -e 's/[";]//g')
GITTAG  = $(shell git describe --always 2>/dev/null)

### The directory environment:

# Use package data if installed...otherwise assume we're under the VDR source directory:
PKGCFG = $(if $(VDRDIR),$(shell pkg-config --variable=$(1) $(VDRDIR)/vdr.pc),$(shell pkg-config --variable=$(1) vdr || pkg-config --variable=$(1) ../../../vdr.pc))
CFGDIR = $(call PKGCFG,configdir)
LIBDIR = $(call PKGCFG,libdir)
LOCDIR = $(call PKGCFG,locdir)
PLGCFG = $(call PKGCFG,plgcfg)
#
TMPDIR ?= /tmp

### The compiler options:

export CFLAGS   = $(call PKGCFG,cflags)
export CXXFLAGS = $(call PKGCFG,cxxflags)

### Regexp
ifeq (exists, $(shell pkg-config libpcre && echo exists))
	REGEXLIB = pcre
else
$(error PCRE library required)
endif

### The version number of VDR's plugin API:

APIVERSION = $(call PKGCFG,apiversion)

### Allow user defined options to overwrite defaults:

-include $(PLGCFG)

### The name of the distribution archive:

ARCHIVE = $(PLUGIN)-$(VERSION)
PACKAGE = vdr-$(ARCHIVE)

### The name of the shared object file:

SOFILE = libvdr-$(PLUGIN).so

### Includes and Defines (add further entries here):

INCLUDES +=

DEFINES += -DPLUGIN_NAME_I18N='"$(PLUGIN)"'

ifneq ($(strip $(GITTAG)),)
DEFINES += -DGITVERSION='"-GIT-$(GITTAG)"'
endif

### The object files (add further files here):

OBJS = $(PLUGIN).o blacklist.o charset.o config.o epgclone.o epghandler.o regexp.o setup_menu.o tools.o

ifeq ($(REGEXLIB), pcre)
LIBS += $(shell pcre-config --libs-posix)
INCLUDES += $(shell pcre-config --cflags)
DEFINES += -DHAVE_PCREPOSIX
endif

### The main target:
